Relevance.The need to continue studying the patterns of distribution of physical properties of rocks by area and compare with previously conducted studies on the analysis of the distribution of rock density.Generally accepted approaches imply averaging constants, which are key in calculating the filtration-capacitive properties.A small amount of ac
Geological characteristics and models of fault-fold-fracture body in deep tight sandstone of the second member of Upper Triassic Xujiahe Formation in Xinchang structural belt of Sichuan Basin, SW China
In the second member of the Upper Triassic Xujiahe Formation (T3x2) in the Xinchang area, western Sichuan Basin, only a low percent of reserves has been recovered, and Music Art the geological model of gas reservoir sweet spot remains unclear.Based on a large number of core, field outcrop, test and logging-seismic data, the T3x2 gas reservoir in th
Bifurcation and complex dynamics of a discrete-time predator-prey system involving group defense
In this paper, we investigate the dynamics SUNSCREEN SPF 40 KIDS of a discrete-time predator-prey system involving group defense.The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically.It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interio
Evaluating the Open Source Data Containers for Handling Big Geospatial Raster Data
Big geospatial raster data pose a grand challenge to data management technologies for effective big data query and processing.To address these challenges, various big data container solutions have been developed or enhanced to facilitate data storage, retrieval, and analysis.Data containers were also developed or enhanced to handle geospatial data.
A Hybrid Method for Numerical Solution of Fuzzy Mixed Delay Volterra-Fredholm Integral Equations System
Rolling Helper A hybrid method for the numerical solution of the system of delayed linear fuzzy mixed VolterraFredholm integral equations (FMDVFIES) is introduced.Using the hybrid of Bernstein polynomials and blockpulse functions (HBBFs), an approximate solution for the equations system is provided.Firstly, the HBBFs and their operational matrices
